The Deluxeware DX4015 First Model Denim Jacket represents an evolution in classic denim outerwear. Constructed from dark blue Rogue unsanforized denim woven in Ibara, Okayama Prefecture, this jacket transcends typical vintage reproductions by fusing original design authenticity with modern aesthetic sensibilities.

The fabric is the brand's No.5 Denim 15oz "Rogue Denim", woven on vintage shuttle looms using American cotton No.6 yarns with an uneven warp and a straight weft. This combination of wildly uneven warp construction and deep dark indigo coloration produces the brand's signature vertical drop fading and distinctive aging characteristics — qualities that develop more dramatically with every wear.

Sewing takes place entirely in-house in Odate, Akita Prefecture, using Union Special sewing machines and a vintage stitch methodology developed specifically for period-correct results. The technique employs 14 types of sewing thread with a 5–8 stitch needle pitch to create natural puckering and time-evolving stitching characteristics — small details that quietly bring the construction closer to the originals.

The First Model Denim Jacket embodies the 1950s rebellion spirit while meeting contemporary style standards. Made from 100% cotton and finished with a flasher and the brand's signature red tab, this jacket is built for true Japanese vintage repro purists.

Fit Notes: This jacket fits true to size or slightly small for Deluxeware and most Japanese brands. Compared to most global American brands, a size 42 fits similarly to a standard American Large or even Medium. We recommend taking your usual size, or sizing up one if you prefer a more relaxed fit. The fabric is unsanforized but has been one-washed, so no further shrinkage is expected. As always, we strongly recommend checking our size chart and comparing it with your best-fitting jacket to find the perfect size.
